K-5 vs K-5 II(s): shutter (mirror) noise?

Hi All,

I've not been able to find any videos of the K-5 II being directly compared with the K-5 in terms of shutter or mirror noise. I know that the K-5 is very good in this department, and would just like to check that the K-5 II and IIs deliver the same benefit. If the K-5 II models were even slightly louder, it would be a reason for me to get a K-5.

Thanks.

PS: For the benefit of anyone else interested, here's a video where you can hear the shutter, but there's a lot of background noise, which makes it hard to assess how loud it might be:
